Resolved CRT Monitor GR2D Error, Fix Provided Not Great for CRT

Hey y'all, I installed Legends and was met with the common GR2D error. I followed the fix provided however one of the steps (and what seems to be the vital step in my case) is to flip the refresh rate to 60hz. If you do this on a CRT monitor, you get some hardcore flickering and it definitely leads to a headache pretty quickly. Is there any way at all to get the game to run with your monitor running at any other refresh rate? I'm curious as to what the cause is to this issue as well. Currently, I cannot play the game as I cannot run the game with my monitor set to a refresh rate > 60hz . I hope there is a workaround, and if not I would be happy to try whatever y'all suggest. Here is (the gist of) my setup:

2 GTX 980 TIs each running a 1280 x 960 CRT at 93hz
Intel i5-7500 @3.40ghz
32gb DDR4 Ram
Windows 10

As I stated previously, I have already followed the pinned fix for the GR2D error.

Thanks!
